The apps

Three apps. Three very different problems.

From staying close to friends to a relaxing chain-reaction puzzle. Each app is shipped, signed, and shaped by one person who actually uses it.

About

One developer, building things that should exist.

I'm Simon, a software developer based in Germany. I work on apps because they let me put complete, polished little tools directly into people's pockets.

Every app on this site was designed, coded, tested, and shipped by me. Hey Buddee is privacy-first because friendship data should stay yours. The games (Kiwi and Chain Balls) are supported by ads so they can stay free for everyone.

🧭

Focused

Each app does one thing, and tries to do it really well.

Honest

Hey Buddee keeps your data local. The games are ad-supported and free.

Crafted

Native iOS, considered details, smooth animations.

🛠️

Independent

Shipped by one person. Honest about what's done and what isn't.

Have an idea, or just want to say hi?

I'm always happy to hear about new ideas, bug reports for any of the apps, or just nice emails from people who use them. Drop me a line.
